SPECIFICATION forming part of Letters Patent N0. 772,383, dated October 18, 1904.

To all whom it may concern.-

Be it known that I, HERMANN J AOOB MARTIN SIEMERS, a citizen of Germany, residing at Hamburg-Horn, Germany, have invented new and useful Improvements in Water-Motors, of which the following is a specification.

v The motor according to this invention is intended to utilize the current streams for industrial purposes without being affected in any way by change in the current or by the formation of ice in the stream. To this end the motor is arranged vertically in a conduit of special form open at both ends, which conduit, so as to be independent of frost, is placed deep in the water in order that the current can continue to'freely work the motor under the ice.

In the accompanying drawings, Figure 1 is a vertical cross-section of my improved water-motor on the line A B of Fig. 2; Fig. 2, a horizontal section on the line C D of Fig. 1, and Fig. 3 a longitudinal section on the line E F of Fig. 2.

The conduit consists of a lower air-chamber a, on which are arranged air-chambers 6 and c, forming lateral walls, and tapering airchambers d and e, forming an intermediate interrupted partition-wall. The double channel thus produced is closed at the top either by a plate f, as shown in the drawings, or by another air-chamber. The upper air-chambers communicate with the lower one, a, by means of openings 9 or in any other suitable way, and the chambers are of such a shape as to form two diagonallyarranged tapering inlet-passages and two diagonally-arranged outlet-passages it, all of which communicate with each other at the center. The outletpassages h are provided with sluice-gates 7c and Z. In the open portion of the central partition rotates the centered vertical motorspindle m, supported in a pivot-bearing n and a journal-bearing 0, which are suitably constructed so that the friction is reduced to a minimum; On the motor-spindlem are arranged vanes, paddles, or buckets p, the open sides of which take up the impact of water and cause the spindle m to rotate, while the wedge-shaped opposite sides of the paddles p out through the water like knives, so that the close automatically, and water will enter through the adjoining funnel-shaped inlet of the channel and open the gate 7:. The current acts in this case on the motor-spindle m in the opposite direction, but causes it to rotate in the same direction as before.

The gates and Z are hinged upon vertical rods and are protected against excessive back play by stops Q01 in some other way. The transmission of the power generated by'the rotation of the motor-spindle m (which always takes place in the same direction) to the shaft tcan be effected in any desired manner. In the drawings it is shown to be effected, by way of example, by means of bevel-gears '2,

Fig. 1.

The volume of the air-chambers a 7) 0 (Z a is calculated in such manner that when said chambers contain air only the whole apparatus will float on the water and can be easily towed to the desired point. Theisinking of the apparatus is effected by opening one or several valves in the bottom, whereupon the hollow chambers will fill with water. After the apparatus has been properly anchored or secured by cables in the bed of the stream it may begin to work at once. When it is required to examine the apparatus or to effect repairs, the bottom valve o is closed and the water pumped out from the chambers through the pipe 10, when the apparatus will rise to the surface. In order to prevent more water from entering through the valve '0 during the pumping operation, the valve can be secured by means of the suction-pipe a, which can be screwed down in a casing w and is perforated at the bottom, said suction-pipe 14 being provided at the top with an angular head .9 for the purpose of receiving a spanner or the like. After this has been done the closing-cap w is removed from the pipe to and the latter connected to a pump in any suitable manner.

The inlet-openings can be closed by means of flexible shutters y, Figs. 2 and 3, passing over rollers .2. By these means the motor can be stopped under Water Whatever be the direction of the current.

What I claim is- 1. In a water-motor, the combination of a body provided with air-chambers, with a Water-inlet valve, and a suction-pipe having a perforated lower end and adapted to close said valve, substantially as specified.

2. In a Water-motor, the combination of a body provided with a series of air-chambers, with a water-channel having diagonally-ar-
